Descubrimiento de Pitcairnia undulata Scheidweiler (Bromeliaceae) en Tabasco, México

Acta Botanica Mexicana, 1988
Se registra por primera vez la presencia de Pitcairnia undulata Scheidweiler en México. La planta se colectó en las laderas calizas del Cerro del Madrigal, cerca de Teapa, Tabasco y se identificó como P. undulata, a pesar de las diferencias en el tamaño de algunas estructuras entre los ejemplares de Tabasco y la descripción original de la especie.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae). [PDF]

Am J Bot
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset. [PDF]

Ecol Evol
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

Through the eyes of the Andean bear: Camera collar insights into the life of a threatened South American Ursid. [PDF]

Ecol Evol
This study used a camera‐equipped GPS collar on a male Andean bear in southeastern Peru, revealing rare behaviors like courtship, novel diets, and geophagy. These findings from the Kosñipata Valley provide valuable insights into the poorly understood ecology of Andean bears and suggest many areas for further research.

AngleCam: Predicting the temporal variation of leaf angle distributions from image series with deep learning

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2531-2545, November 2022., 2022
Abstract Vertical leaf angles and their variation through time are directly related to several ecophysiological processes and properties. However, there is no efficient method for tracking leaf angles of plant canopies under field conditions. Here, we present AngleCam, a deep learning‐based approach to predict leaf angle distributions from horizontal ...

A 100‐Million‐Year Gap in the Knowledge of the Evolutionary History of Bromeliaceae: A Brief Review of Fossil Records

Feddes Repertorium, Volume 132, Issue 1, Page 20-27, March 2021., 2021
Bromeliaceae arose in the Early Cretaceous, diverging from Typhaceae at ca. 125 Ma. After an apparent evolutionary stasis of 100 million years, they have undergone a high diversification starting in the Miocene. By adding fossils to the phylogenies, one can infer dates of arising and the divergence of lineages and link them to geological and climatic ...
